To all whom it may concern:

B'e it known that I, WILLIAM J AeoBsoN, a citizen of. the United States, and a resident of Chicago, 4in the county of Cook and State of Illinois, have -invented a new and useful Improvement in Roof Flashings, of which the followingl -is a full, clear, and exact d escription.

My invention relates to improvements in,

roof flashings and it Aconsists in the combinations, constructions, and .arrangements herein describe-d and claimed.

4In the construction of roofs, especially those roofs of brick buildings in cities, great trouble has been experienced in preventing leakage along the edges ofthe' fire wall. It

has been customary to' make use/,o a composition flashing which is placsdalong theroof and isbent up againsttheiire/wall and held to the fire wall by a lath which isnailed often into green mortar. Such a construction can only last for a limited time, because the nails do not hold well inthe green mortar, the lath becomes loosened, and the flash- 2 ing pulls away .from the' wall, thereby allowing leakage. Y v n An object of'my invention is to provlde a construction whereby leakage is prevented and the life of the roof is greatly augimented,

.A further object of 'my invention isto provide a roof flashing construction whichl requires no nails or lath; that can be applied quickly, and will retain the flashing securely. O

provide a lflashing construction which may be used when it is desired to replace the flashing, thus bviating the necessity of providi-ng new -iashing retainingmeans.

"As-@Ether -object of my invention is to provide a means for retaining Q flashingwhich permits the wall to settle without any danger provide a means for retaining liexible flashing s uch as composition flashing, wh1ch 1s inexpensive, and which can be readily 1n-l lstalled. vOther objectsand advantageswill appear in the following specification, and the novel features of the invention will beparticularly pointedout in the appended claims.

My invention is illustrated 1n the accom- A further object of lmy invention is to ip-anying drawings-*forming av part of this application in whlch:

Figure 1 is a ysectional view of my improved flashing construction for roofs, and

Figure 2 is a perspective view of a portion of the flashing retaining means.

Inthe drawings I have ifiud-ieated the roof T he fire vwall I have indicated in dotted lines at' 2. As willbe seen from 1, the ire wall is shown in section. In carrying out myl invention I provide 05 a sheet of'metal 3 which may be galvanized Iron, copper, or any suitable material. This sheet has-a flange 4 at one edge thereof. Parallel with the flange 4 is an S-shaped 'bend 5 having an integral portion 6 extend- -70 ing normally parallel with the portion 3.

vThe sheet 3 is laid in the wall by placing `1t on top of one of the bricks such as the brick 7 1n Figure l, and lplacing thereon mortar 8, after which the upper bricks-7 are laid in 75 the ordinary way. It will be noted that the front edge of the S-shaped bend 5 is flush with the outer face of the wall, while normally the portion 6 extends outwardly at right angles to the wall, as shown in Figure?lo 1. Sheets similar to 3 are laid continuously in the tire-wall around the edges of the roof. Aand as will be seen from Figure 1, at some f distance above the roof.

"f In Figure 1 I have indicated at 9 composi- 85 tion flashing. This is bent up along the face of the wall in the usual manner, but instead of. being held by lath which is nailed to the wall, it is held by means oi a retain- A further object of my inventlon 1s to.-

ing plate 10 which, as will beI seen from 90 Figure 2, is provided with a -flange 11 at its upper end, arranged to .enter a socket 12 in .the S-shaped bend 5. The lower end of the plate 10 is bent outwardly as shown at 13, but is disposed normally above the flashing.

. The plates 10 are secured in'positionso as vto hold the flashing 9 ,against'the iire wall,

the flashing is protected.

' not come loose, and thus theupper edge o Shouldl the Wall settle, the plate 3 and the plates l() Will merely settle, but the flashing will still be protected, and thus there will be no danger of leakage at the edge of the roof.' Even should a drain spout be clogged up so that the roof is Hooded and the Water should rise above the plate 3, it `would be prevented from running down the' fire Wall A y the S-shaped bend 5.

I claim:

1. The combination with a roof, a re Wall, and flashing contiguous to `said roof and said lire Wall, of a horizontal plateearried by said re Wallabove said roof, said 'platehaving an S-shaped bend to 'constitute a socket, and a portion extending beyond said socket normally parallel with the roof,

a retaining plate having a flange at its upper edge arranged to enter said S-shaped'soeket, the inner face of said retaining plate engaging with said lashing,and the outer face being arranged to be engaged by the extend ed portion when the latter is bent downwardly.

2. The combination with a roof, a re' wall, flashing contiguous' to said root` and said fire Wall, of arhorizontal plate carried by said fire Wall above said roof, said plate having a flange at one edge thereof arranged to enter behind a portion of the wall for reventingthe withdrawal of the plate, and v eing provided with an-S shaped socket parallel to said 'lange,'and having a portion arranged to extend beyond said socket normally parallel with the roof, a retaining plate having a flange at its upper ed e arl ranged to enter said S shaped socket, t ein'- ner face of said retaining plate engaging with saidlashing, and the outer aee'1being arranged to be engaged by the extending portion when the latter is bent' downwardly.v
